What is the molar mass of a polyvinyl acetate polymer single chain containing 1517 repeat units?
it is the molar mass of one (86g/mol) multiplied by 1517 which is 130462 g/mol
How many moles are there in 20.67g sodium chloride?
To find the number of moles in 20.67g of sodium chloride, you need to first calculate the molar mass of NaCl (sodium chloride), which is approximately 58.44 g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 20.67g divided by 58.44 g/mol is approximately 0.354 moles of sodium chloride.

How many milliequivalents of a chloride ion are in .725 grams of chloride?
To calculate the milliequivalents of chloride ions in 0.725 grams of chloride, you first need to determine the molar mass of chloride (Cl⁻) which is 35.45 g/mol. Next, calculate the number of moles in 0.725 grams by dividing the mass by the molar mass. Then, convert moles to milliequivalents by multiplying by 1000 (since 1 mole of ions = 1000 milliequivalents).
How I will make 3 Molar solution of potassium chloride in 250 milliliter?
To make a 3 Molar solution of potassium chloride in 250 milliliters: Calculate the mass of potassium chloride needed using its molar mass. Dissolve this mass of potassium chloride in a small amount of water, then add water to bring the total volume to 250 ml. Stir to ensure complete mixing and dissolve the potassium chloride completely.
Calcuate the mass of sodium chloride produced if 12.3 g of sodium oxide reacts with an excess of calcium chloride?
To calculate the mass of sodium chloride produced, first balance the chemical equation for the reaction between sodium oxide and calcium chloride. Next, determine the molar ratio between sodium oxide and sodium chloride in the balanced equation. Finally, use the given mass of sodium oxide and the molar mass of sodium chloride to calculate the mass of sodium chloride produced.
The molar mass of aluminum chloride is grams?
The molar mass of anhydrous aluminum chloride is 133,34 grams.
When 1 gram of zinc chloride ZnCl2 is dissolved in water the heat evolved is 0.53kJ Calculate the molar heat of substance of solution of zinc chloride?
To calculate the molar heat of solution of zinc chloride, we use the heat evolved by dissolving 1 gram of ZnCl2 in water. First, we convert the mass of ZnCl2 to moles using its molar mass of 136.3 g/mol. Then, we divide the heat evolved by the number of moles dissolved to get the molar heat of solution. In this case, the molar heat of solution would be 3.89 kJ/mol.
How many moles of potassium chloride are there in a 100.0g sample of potassium chloride?
To calculate the number of moles of potassium chloride in a 100.0g sample, you need to divide the mass of the sample by the molar mass of potassium chloride. The molar mass of potassium chloride is approximately 74.55 g/mol. Therefore, 100.0g ÷ 74.55 g/mol = approximately 1.34 moles of potassium chloride in the sample.
Now assume you measure out exactly 2.0 ml of aluminum chloride into a third test tube How many moles of aluminum chloride are in the tube?
To calculate the number of moles of aluminum chloride in the test tube, you need to know the molar mass of aluminum chloride (AlCl3). The molar mass of AlCl3 is 133.34 g/mol. Given that you have 2.0 ml of AlCl3, you will need to convert this volume to grams using the density of AlCl3. Finally, you can calculate the moles using the molar mass.
What is the mass of 0.0435 mol zinc chloride?
To find the mass of zinc chloride (ZnCl2) in 0.0435 mol, you need to calculate the molar mass of ZnCl2, which is 65.38 g/mol. Multiplying 0.0435 mol by the molar mass gives a mass of approximately 2.84 g.
